getCurrentInstructionSet fail:

Error message

getCurrentInstructionSet fail:

What it means

SharePatchFileUtil.optimizedPathFor computes the /oat/<isa>/xxx.odex path on Android O+. It calls ShareTinkerInternals.getCurrentInstructionSet(); if that throws (reflection into VMRuntime or unreadable Build.CPU_ABI), it is rethrown as TinkerRuntimeException('getCurrentInstructionSet fail:'). The odex location cannot be computed without knowing the ISA, so this is fatal to the dex-opt step.

Solutions

1. Ensure tinker is up to date — newer versions read the ISA via supported APIs or cached values compatible with hidden-API restrictions.
2. Check whether your app targets a SDK where Build.CPU_ABI is deprecated/empty (API 21+ multi-ABI) and rely on tinker's own detection instead of custom pre-checks.
3. If you wrap this call yourself, catch TinkerRuntimeException and disable tinker's dex-opt path for that process (e.g. only load patch in the main process).
4. Verify no proguard rules keep-away the android.os classes or tinker reflection helpers.

Example fix

// before
String odexPath = SharePatchFileUtil.optimizedPathFor(dexFile, optDir); // fatal if isa lookup fails

// after
String odexPath;
try {
    odexPath = SharePatchFileUtil.optimizedPathFor(dexFile, optDir);
} catch (TinkerRuntimeException e) {
    ShareTinkerLog.w(TAG, "isa lookup failed, skip custom odex path", e);
    odexPath = new File(optDir, dexFile.getName() + ".odex").getAbsolutePath();
}

try { path = SharePatchFileUtil.optimizedPathFor(dex, dir); } catch (TinkerRuntimeException e) { /* skip custom odex path, use default dir */ }

When it happens

Trigger: Any exception inside getCurrentInstructionSet(): reflection failure calling VMRuntime.is64BitRuntime (hidden-API blocking on newer Android), Build.CPU_ABI returning empty or an unrecognized value, or class-not-found on heavily restricted ROMs.

Common situations: Non-SDK interface restrictions (Android 9+ greylist) breaking the VMRuntime reflection; emulators or obscure ABIs; proguard/R8 stripping or renaming touching the reflection path; running in processes where the runtime is atypical (isolated processes).
